- Familiarity: I've put it through the wringer
I find this item fully functional from -15F to warm spring days; that being said with my jacket zipped over my face at the colder temps. As well I run very warm over all. This does not hold condensation from breath too much and dries quickly. Its not perfect, so I will not rate it 5 stars, but if I could I would rate it 4.75.
